production of a wrench wherein a sunple and and claimed. 1' p In the accompanying draw ng: Figure 1 is a side elevation of the wrenchfiasconstructed s w t r ymn To all whom it may concern:

Be it known that 'L-Onn Hrlilunnum c1 1- zen of the United States, residingat nion, .in the county of Cavalier and State ofNorthhave invented certain-new and use ful Improvements in Wrenches,. of which-Q the following is aspecification, referencebe 1 5 Dakota,

ing had therein to the accompanying drawmg.

simple and efficient means for adjusting the slidable jaw whereby'thevarious sized nuts may be easily accommodated whendesired.

Another obj ect of this invent on is the eflicient means has been'provided for positively retaining the sliding jaw man adjusted set position when the devrceis 1n op- 20 eration.

With these and other objectsiniziew, this invention consists of certain novel combinations, constructions, and arrangements of parts, as will be hereinafter fully described in accordance withthis'inventi on. Fig.2; is a front-elevation of the wrench. Fig. 3-fiis;a-

sliding jaw.,

Referring to the; accompanying drawing [by numerals it will be seen that the wrench .comprises a shank 1 having a fixed jaw 2 formed upon one end thereof, While the opposite end terminates in the gripping portion 3. This shank-1 is provided with a lon- V, gitudinal slot'4 adjacent the fixed jaw 2, .and.- it, is also provided witha plurality of-rack teeth 5 formed-upon its rear side edge.

The sliding j'aw comprises a body portion 6 having integral rearwardly extending side; portions 7 which are constructed soas'to extend in parallelspaced relations relative to each other. Thesesides 7 are provided with registeringapertures 8 and 9 through which the retaining bolts 10 and 11 are adapted.

Therefore, a piece. of wire may pass through 7 .these cut-out portions-and through the-longitudinal slot 4 wherebythe device may be .used also as a wire cutter by swinging the: i

to pass. These bolts 10 and 11 also pass through the longitudinal slot 4 formed in the; 56 shank 1 thereby positively retaining the sliding jaw upon the shank 1 in such a man i t a ntraeaers rtent. Patented May 1 .oii i1ieafmnt 18-, .1015. sent! a. 34, i

This invention 'relatesto a wrenchandha s 1 for its principal objectthe production of a onwhen necessary. 'The adjusting lever.

jacent one end, with the gripping portion13 whichis adapted to theform soas to be adracent the-gripping portion 3 of'the shaft, 1. he opposite end of this grippinglever 13 is bifurcated as shown at 14 so-as-tofprovide the ears 15; These ears 15 are adapted tofit upon elther side of the shank 1 thereby emwith registering apertures 16 through which the bolt 11 passes for pivotally retaining the lever 12 in an engagement with the movable jaw of the shank. This lever 12 is also provided with rack teeth-17 formed upon its inner portion and being so constructed as to come into engagement with rack teeth 5 of the shank ,1 when the lever 13 is swung t0- wa'rd theshank 1 as shown in Fig. 1. By referring particularly to Fig. 6 .it will be- "seen that the. inner portions of the side 7 of the sliding jaw 6 are notched as indicated at lever 12.

In a wrench of. the class described, the combination of a. shank having a fixedjaw,

said shank provided with a longitudinal slot adjacent said fixed edge of said shank, a sliding jaw mounted upon said shank, said sliding jaw provided 1 with enlarged parallel side portions embracsaid side portions being provided with a shallow internal notch adjacent its outer end, whereby said notches will be formed in alinement with each other, means passing teeth of said shank when it is desired to move through said side portions and said slot for slidably retaining said sliding jaw upon said slidingjaw or retain the same in a set position,-said side portions of said sliding I jaw being adapted to. guardsaid ears of said lever, whereby said ears will be protected from injury when in use.
